Please help me!!! Homework #19: Shopping List Application In Java

In this assignment, you will create an interactive table-based shopping list application. Create an Item class that stores shopping items: a String called name, a Double called price, and an Integer called quantity. Create the corresponding get/set methods for each. Create a class called ShoppingList that extends the JavaFX Application class, and contains a TableView (with columns for Name, Price, and Quantity) that displays an ObservableList of Item objects. The list should initially be empty. The TableView should be editable. At the bottom of the application, create an area that allows a user to add a new item to the list, including Labels that display the words Name, Price, and Quantity and a TextField next to each. There should also be an Add button that, when pressed, uses the information stored in the textfields to create a new Item and adds it to the list (which will then be automatically stored in the table). Finally, add a button Total Price that, when clicked, calculates the total price of all items currently in the list (add together the price * quantity for each item in the list), and display the total in a label.
